Preflop: 3bet more - $0,24. You want to build the pot if you hit. And especially since you're OOP.

Flop: When he calls 3bet I don't put him on FD. Slowplaying wouldn't me advice so I would cbet a bit more than 1/2 pot.
Second option would be to c/r if you know opponent gets aggressive when he senses weakness. Straight forward play is better though.
